Here's the breakdown:
* Persian cats: Typically have litters of 3-5 kittens.
* Breeding for size: Breeding for smaller sizes can lead to health problems in cats.
* "Teacup" cats: Often suffer from health issues due to selective breeding for size.
It's crucial to prioritize responsible breeding and the health and well-being of cats. Adopting a cat from a reputable shelter or breeder is always the best option.
